You have several graphical tools that can get you started, but nothing replaces learning to code. I suggest you take a look at bluefish. Tools such as kompozer are "OK" for starting, but they write long sloppy code and at some point you will almost certainly need to debug it.

Best way: take an editor (gedit) and learn html yourself. You do not need an IDE for that! And you will learn coding from the beginning, you will understand what you re doing. Look at selfhtml.org if you understand german or french this is the best choice for you.

Others have mentioned several WYSIGYG (what you see is what you get) editors. However, they're quite limited. If simplicity is what you're after, I recommend something like Google Sites. But really, you should learn HTML and CSS. They aren't too difficult, and they'll open up many possibilities. In my opinion, except for quickly-thrown-together sites, you want to write the site yourself.

Suggested editors: Everyone has their own favorites. I mostly use Gedit and VIM. Others have other preferences. No matter. Any decent editor will have HTML support built in.
